Unlimited Mobile to Any Mobile is available to AT&T customers with an unlimited messaging plan and a qualifying voice plan. AT&T has yet to define which voice plans will qualify for the new feature.

“Mobile to Any Mobile is an exciting offer that will keep our customers connected to the people they want to talk to, when they want to talk to them, without the hassle of watching minutes,” said David Christopher, chief marketing officer, AT&T Mobility and Consumer Markets. “We’re giving customers more options and even better value. And when you include Rollover Minutes, a benefit available exclusively from AT&T that lets customers keep their unused minutes for all domestic calls, including to landline numbers, it’s clear that AT&T offers the most flexibility in the industry.”

Unlimited messaging is available for $20 per month on an individual line and $30 per month for a FamilyTalk plan of up to five lines.

Existing customers will need to visit www.att.com/anymobile on or after Feb 10th to activate the feature.

What say you? Do you think this adds significant value to the offerings from AT&T or do you perceive this as a desperate attempt to keep fleeing customers? Let me know in the comments below.
